Is it a simple procedure to replace the trunnions? Screw the old ones out and screw in the new ones? No gunsmith needed?
I have 2 Beretta's and they are both tight. But, I've wondered how to replace the trunnions if needed.

The trunnions (i.e. hinge pins) must be fitted to the barrel monoblock slots. Simply swapping in larger pins without proper fitting will compromise the lockup. The hinge pins, however, rarely need to be changed. Changing to the next size locking bolt (a $35 part) is usually enough to tighten up the 680 action.
